Colossal Modulation of Mechanical Resonance with temperature in single‐Crystalline SrTiO3 Microbridges Integrated on Silicon

open access: yesAdvanced Electronic Materials, EarlyView.
The structural characteristics and resonant mechanical behavior of suspended microbridges comprised of single‐crystalline SrTiO3 that has been grown on silicon are presented. Due to differences in thermal expansion between the SrTiO3 and silicon, we find that the resonant frequencies of the microbridges are not only enhanced, but also hyper‐sensitive ...

Negative Feedback in Hf0.5Zr0.5O2 Resistive Memory: Feigenbaum Route Toward Two‐Terminal Pseudo‐Random Number Generation and Neural Network Instabilities

open access: yesAdvanced Electronic Materials, EarlyView.
Resistively switching TiN/Hf0.5Zr0.5/Au valance‐change memory devices show period‐doubling bifurcations, arising from competing influences of filamentary counter‐eightwise filamentary switching and eigthwise electrochemical oxygen exchange at the active electrode.

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

open access: yesEcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Harnessing Thin‐Film Solid‐State Electrolytes: Enabling Breakthroughs in All‐Solid‐State Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration highlighting the advantages of transitioning from traditional thick solid‐state electrolytes (SSEs) to thin‐film SSEs. Thinning the electrolyte enables higher ionic conductivity, reduced interfacial polarization, improved flexibility, compact electrode contact, and enhanced energy density, offering a promising pathway toward high‐

On‐Farm Demonstration and Economic Evaluation of an IoT Sensing System for Irrigation Management in South Carolina

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Irrigation can strongly influence agricultural productivity and sustainability. While sensor‐based irrigation has the potential to improve yield, reduce input costs and enhance resource‐use efficiency, its adoption in commercial agriculture remains limited.

Reflectometry, ablation and fluid retrieval with an optical fiber

open access: yes, 2010
A technique combining low-coherence reflectometry, laser ablation and microfluidics in a single microstructured fiber is developed. Experimental results demonstrate the possibility to ablate thin aluminum foil samples with fiber-guided Nd:YAG laser light,

Micellar and Solubilization Properties of Biological Surfactant Surfactin

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.
